On my home network, my iBook, iPad, and Acer laptop running Win 7 has no trouble accessing web pages including facebook. My desktop however will not load facebook but has no trouble accessing other web pages. On my desktop, I use firefox but have tried IE 9.0 & Chrome with similar results. I even went to dos command prompt and pinged facebook. It was the correct url.
Any idea what is going on? And how do I fix it?
